Metal Key-Pad Dome Switches

Keystone’s tactile Key-Pad snap dome action switches are ideal for keypad arrays

Image of Keystone's Metal Key-Pad Dome SwitchesKeystone's innovative "Key-Pad" dome switches feature a 4-legged shape that allows them to be durable and reliable while maintaining an exceptional tactile feel. Offered in mini (0.331" diameter), compact (0.394" diameter), and maxi (0.480" diameter) styles with trip forces from 7.8 oz. to 14.8 oz. These "Key-Pad" domes offer design versatility for single- or double-sided printed circuit boards, flex circuits, and membrane switch panels. Manufactured from nickel-plated stainless steel, these domes are built for harsh environments such as microwaves, vending machines, or any application requiring substantial tactile response along with extensive actuation life. Adhesive backed spacer material for creating custom "Key-Pad" arrays is also available. Spacer material is designed to provide the proper spacing between the circuit board, the dome, and the device graphic layer. Made from clear polyester, the spacer material is supplied in sheets for customization and assembly/inspection ease.
